I bought this because my child started standing up a lot while I was feeding them! It was super convenient☆ There are no noticeable stains at a glance, but please be aware that there is some wear and tear, such as fraying on the belt. It's very easy to use, just snap it onto the back of the chair. Please check the last photo for the size.
